Mathematics, math research, mathematical modeling, mathematical programming, math articles, applied math. The complex inverse trigonometric and hyperbolic functions in these notes, we examine the inverse trigonometric and hyperbolic functions, where the arguments of these functions can be complex numbers. Because these numbers are a composition of dual, complex and hyperbolic numbers, we think that it would be better to call them hybrid numbers instead of the generalized complex numbers. These derivatives follow a very familiar pattern, differing from the pattern for trigonometric functions only by a sign change. The first section is a more mathematical definition of complex numbers and is not really required for understanding the remainder of the document.
